Onkyo sl107 replacement power transformer

Any idea where i could order a transformer with number TTI230010120 or can I use a similar type this being a 230v/100w but what is the secondary voltage ,.It has three wires obviously centre tapwith twowhat I think is 12v output

SOURCE: JCR-160 clock radio Clock running slow

The clock works off the frequency (hertz). In US the electrical wave frequency is 60HZ/sec and in India and many other countries 50HZ/sec. Hence, the clock slows down about 6 seconds or so every minute.

SOURCE: No power when plugged in. On off button stays dark, nothing works

Everyone has problems with SMPSs; mine started in 1971 when IBM was first using them; they were literally blowing up and throwing molten copper several feet.
Anyhow, if you have the benefit of a capacitance meter with DF function, check the main filter caps all of the smaller caps. The quality and durability of electrolytics is bad and getting worse and once one of these fails anywhere in a feedback path, the supply will not start. HF is hell on electrolytics.
The (ferrite) transformer in a switcher measures very low on the Ohms scale; depending on power handling and service frequency, primary <<100 Ohms, secondary from 0.? - 10 Ohms between taps, because they operate at higher frequencies. The 50 volts from the diode bridge is way too low; you probably have failed 100-200 uFd. electrolytics right close to them although this is fairly rare since they are only working with 120 Hz. From a 120 VAC line, you should have ~ 160-170 DC volts at no load if the caps are still working as they should and you have no notable resistance between the AC and the diodes.
Well-designed switchers are wonderfully efficient and very reliable if the maker didn't cheat on component quality. I've repaired literally thousands as a sideline in a now retired business and after studying them and adding a ceramic cap.or two and better quality electrolytics, they will run for decades. At one time, I had standard repair prices on ~ 70 different models.
My guarantee was 'lifetime' and that was limited only because I retired.

The type of audio power and the number on onkyo A917 amplifier


Hi
Usually there are 2 transistors for each channel, if you don't know the numbers on the transistors.
there is another way to get as close as possible to have equal or similar to the same type of transistors (NPN/PNP)
example: 2SA is PNP transistor.
there are (2SA/2SC) transistors and there are (2SB/2SD)
complementary transistors
1: you have to know the supply voltage for the transistors
2: choose transistors that it is equal to the current and voltage that suits the supply voltage.
follow this link to find suitable transistors.
be aware and be careful that there other parts you need to check on the power amplifier circuit, resistors,capacitors and drivers etc...
I would suggest (2SD1047/2SB817)

If I would buy a Onkyo TX-NR616 in the US (110V) and take it Europe (220V), wouldn't it be a solution to simply exchange the power transformer for a 220v one?


An stepdown transformer is needed should you buy in US and use it Europe

However, if your on a technical side , trace the primary windings , and check

There are European versions which are already 220V, no need to convert.

I have Onkyo HT510 receiver. does not turn "ON".


hi,
There is a standby transformer inside the Onkyo receiver at the mains input stage. If the standby transformer is faulty then the unit will not power on. There will be two transformers. One is big and the other is a small one. The small tarnsformer is the standby transformer. Which will be fitted on a small board where the power cable is connected. Replace the transformer to rectify this problem.
OK

Flyback transformer [LOT] short. Replace the same with similar type and number, and replace the horzontal output transistor alongwith it.

If i accidentally plugged it to 220 volts and it was burned in a seconds can it be repaired?


Good day sir/maam, Yes it can be repaired. if you have plugged in a 110v device to a 220v ac mains, chances are its toast, your onkyo's power transformer is burnt, the repair is replacing the toast power amplifier, or we usually rewind the power transformer specification, after the replacement, you may need to check the power supply section for shorted power regulators, and rectifiers. If you choose to send it for repairs, the service is usually reasonable.

I have a Dacor microwave DMO24 oven which i think is manufactured by Sharp. when the cook function is started it will hum/buzz for about 1 second and then blow a fuse. from the sound, and it's...


It is indeed made by Sharp.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/cap_test.html

http://www.gallawa.com/microtech/xformer.html

OR, we have the service / repair manual for this model and have uploaded it to our site here to help you.

The parts list is here.

You can order Dacor parts
here.

If you prefer to order the original Sharp parts (which are usually considerably less) look for the part number on a tag on the transformer or capacitor (whichever is bad).

The part number for the capacitor will be similar to RC-QZBOl8MREO and the transformer number will be similar to RTRN-BO59MREO. Again, these numbers are examples to show Sharp's number format.

You can order Sharp parts from Encompass here http://tinyurl.com/7qy85y or you can call them toll-free at 866-779-5835.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Seems like Power supply burned up


If the high voltage transformer is fried, the high voltage capacitor or clamp diode may be at least partially shorted (causes transformer overload). Usually this blows a fuse immediately to prevent a transformer burnout. Arcing in the oven waveguide or cavity, or a magnetron fault could also have been the cause. It would probably be a good idea to replace the magnetron controller relay also; it probably was overloaded.

Given the price of the replacement parts, your best bet would be to find a similar unit at an electronics recycling place and combine good parts to get a working oven. The keypad on your oven is worth something since keypad failure is common in that particular line.

Hi if you need a replacement plug for the system then you can buy them from any electrical store but if you want a transformer or anything product specific then you can contact Onkyo USA sevice centre on 201-785-2600.

Here is the Onkyo website where the number is from
. http://www.onkyousa.com/customer_support.cfm

Or for European service centres go here: http://www.eu.onkyo.com/indices/index_com_en_2008_5946251.html

'phones engaged' no sound


Well,
My onkyo receiver was keep displaying "Phones Engaged" and no sound.
All I did was plugged in a phones plug and remove it and for the last 2 weeks there is no problem.
I just happened to have a phone plug (without the actual headphone or wires) and that seems to fix the problem.
Hope it will work you all of you as well.
Good luck.

My Onkyo Receiver TX 601 is turning itself off


Several things can cause this: Loud signal passages can momentarily draw high currents at the mains, especially if you have unit plugged into power stripe with other equipment. Or if unit is plugged into isolation transformer, current draw may exceed output of transformer. Too many speakers hooked to output or if one is bad (partially shorted due to overheating)
